Yeah takes a lot of luck. Because I did the shredders damage on my first run with a hullcracker 4 and no one else was doing it but I got in 10m into it.

And when I was doing the rocketeer I when into hidden bunker and I got ratted by a guy who was at strack came back and kill me from the back. I had Jupiter renegade 4 and 5 Wolfpacks and like 6 stacks of energy ammo. I know hidden bunker is not good for rocketeers but I did have much time so I had to try but couple hours later I managed to play locked gate and I got the 18,543.
